Question

Which of the following statements about gel electrophoresis is correct?a. Longer DNA fragments migrate farther than shorter fragmentsb. Migration distance is inversely proportional to the fragment sizec. Positively charged DNA migrates more rapidly than negatively charged DNAd. None of these statements are true

Answer 1

Migration distance is inversely proportional to the fragment size.

Explanation:

The gel electrophoresis is the process of separation of the DNA fragments after the action of restriction endonuclease action on enzyme. The gel electrophoresis is carried out after coating the DNA fragments with suitable salts and placing them on the side of the electrophoresis table.

The electrophoresis is carried through agar agar gel which has a network inside it.  The smaller DNA fragments will pass more through the gel whereas the larger fragments will be left behind.
